SPECIFICATION forming part of Letters Patent No. 292,253, dated January i2, 18C4,

Y i Application filed September G, 1852. (Modll.)

To all whom, t may concern,.-

Be it known that we, JAMES N. RICE and Josnrrr HUMPHREYS, respectively of Chicago and Austin, Cook county, f Illinois,Y have invented a Combination Lock or Locks, to be applied to doors,'drawers,sashes, gates, &c., of whichl the following isa specication.

Our'invention relates to that class of locks which are applied to drawers, doors, lids, and window sashes; and the nature of it consists in combinations and'constructions, all as will hereinafter be described and claimed, reference being had to the accompanying drawings, in. which- Figure 1 is a front elevation, Fig. 2, a vertical section, showing the bolt drawn back so that the bit is in the slot of the tumblers; Fig. 3, a similar view, with bit in the slot of the loeking-plataso that the tumblers can be revolved; Figs. 4, 5, and 6, perspectives of the three ltumblers; Fig. 7, a perspective of the catch, the plate to which it is attached, and the bolt for operating it; Fig. 8, a rea-r elevation of the shell B, lugs b3, and lockingplate D.

A represents a part of a door, drawer, window-sash, or similar structure; B, the body or shell of the lock, having a notch b2,- C, the bolt, having bit c; D, the locking-plate, having slot d,- E EF E, the tumblers; F, the dial; G, the set-screw; H, the catch; I, studded plate for holding the catch; K, the inclosingplate,which,with the plate I, forms a recess for the catch to move in.

The shell B is attached lto the drawer by straps b, which' have inside screw-threaded lugs b3 for bolts passed through the part A, so that when used upon a drawer or door nothing will be exposed that will permit the shell to be removed. Vithin the shell are three tumblers, E E E?. The tumbler E2 has a screwthreaded extension, e2, which passes through the shell, and is provided with a nut or setscrew, G, which clamps the dial F against the shell. It is also provided with a rear eXtenwhich is provided with a pin, ew. This pin,

when tumbler E is revolved, strikes a pin, 68,:

nut G it cannot be drawn back until the slots,

are again made to register. The end of the bolt-is scarfed at c to form a rigid seat for the catch H, which 'is provided with an aperture,

h, of a shape similar to a cross-section of the v scarfed part of the bolt. The catch H is provided with aiiared slot, h, which embraces a pin, "i, on plate I. This pin serves as' a stop when the catch is in position shown in full lines, Fig. 7, and a second pin, t", serves as a stop for catch when turned as shown in dotted line, Fig. 7.

The operation islas follows: The dial is set so that one figure or a fraction of a figure registers with the notch b2, and the slot e* made to register with the figure. The slots are made to register, as shown in Fig. 2, and the bit c drawn into them. The catch H can now be rocked. By pushing the bolt or key in, as shown in Fig; 3, the catch is held immovably. If the screw G be turned, the register of the slots is destroyed, and the bit can only be drawn back by turning the dial to the combination of gures which make the slots register withy the slot in the locking-plate. `The `combination is used in the same way as the ordinary combination-lock, and further description is unnecessary.

It is obvious that this device, if used upon a window-sash, will prevent a burglar from lifting the latter, even if the window is broken, as he could not see how to operate the dial. Ifplaced upon a drawer, the shell will serve as a handle for operating the drawer.

Vhat we claim as new is- 1. ln alock, the combination of ashell having means for attaching itto a door or other object, tumblers within said shell, having slots and pins which strike each other when the tumblers are turned, a locking-plate to be at- IOO t catch, a scriessof tuinblcrs, one journaled in taehed to the object, and having a slot, d, a bolt having a bit which may be forced into the slot d or drawn into the slot formed bythe tu lnblers, a set-screw for turning the tulnblers, and a catch upon the opposite end of the bolt, and adapted to be turned with the latter, substantially as described.

2. In a lock, the combination of a shell having means for attaching it to an object. and having a movable dial on its face, tumblers within said case having pins and slots, and one having a screw-threaded extension, which extends outside of the shell, a nut or screw on said extension for clamping the dial in place and turning the tuinblers by means of the screw-threaded tumbler, a locking-plate to be attached to the object, and having a bit-slot, a bolt passing through the tumblcrs, and having a bit which may be drawn in the tuinblers slots or forced into t-he slot in the lockingplate, and a catch upon the opposite end of the bolt, and adapted to be turned when the bit is in the tumblers slots, substantially asdescribed.

3. In a lock, the combination of ashellhaving means for attaching it to an object, a bolt passing through the shell and having a bit and the bolt, and having a screw-threaded extension at one end,A a slot at the other, and an intermediate pin, and the others journalcd upon an extension of the first tumbler, and having slots at one end adapted to register with the slot in the first tumbler, and pins attached to and between the tuniblers, and a screw, G, for revolving` the thiinblcs, substantially as described.`

4. In a combination-lock, the combination of a tumbler having a screw-threaded extension, c?, an extension, el, a slot, e4, and a pin, e, a second tumbler journaled upon the extension ci', and having a slot, e7, and pins e and cw, a third tumbler journaled upon extension c, and having pin e and slot e", a screw-nut, G, upon extension c2, a bolt, C, having a bit,

c, which may be drawn into the slots whenk the latter are made to register, and la catch which maybe turned when the bit-is in said slots, substantially as and for the purpose lset forth.
